DIAGNOSIS <TC-SST>

TSB Revision

TWIN CLUTCH- SPORTRONIC SHIFT TRANSMISSION (TC-SST)

22C-25

STEP 1. Scan tool CAN bus diagnostics
Using scan tool MB991958, diagnose the CAN bus lines.
Q: Is the check result normal?

YES : Go to Step 2.
NO :  Repair the CAN bus lines. (Refer to GROUP 54C − 

Troubleshooting 

P.54C-15

.) After repairing the CAN 

bus line, go to Step 2.

STEP 2. Check whether the DTC is reset.
30 seconds after turning ON the ignition switch, check that the 
diagnostic trouble code is reset.
Q: Is DTC No. P0712 set?

YES : Replace the mechatronic assembly. (Refer to 

P.22C-421

.)

NO :  Intermittent malfunction. (Refer to GROUP 00 − How 

to Cope with Intermittent Malfunction 

P.00-15

.)

DTC P0713: TC-SST-ECU temperature sensor system (Output high range out)

CAUTION

• If there is any problem in the CAN bus lines, 

an incorrect diagnostic trouble code may be 
set. Prior to this diagnosis, diagnose the CAN 
bus lines.

• Whenever the ECU is replaced, ensure that 

the CAN bus lines are normal.

.

DIAGNOSTIC FUNCTION

TC-SST-ECU checks that the output of the ECU tem-
perature sensor is normal.

.

DESCRIPTIONS OF MONITOR METHODS

The output of the ECU temperature is determined to 
be too high.

.

MONITOR EXECUTION

• Continuous

.

MONITOR EXECUTION CONDITIONS

DTC SET CONDITIONS

Check Conditions

• Voltage of battery: 8 V or more.
• Voltage of battery: 16.5 V or less.

JUDGMENT CRITERIA

• Fluid temperature: 149° C (300.2° F) or more. 

(400 millisecond)

.

OBD-II DRIVE CYCLE PATTERN

The TC-SST-ECU temperature remains 149° C 

(300.2° F) or less for 400 milliseconds.

.

PROBABLE CAUSES

• Malfunction of TC-SST-ECU

DIAGNOSTIC PROCEDURE

Required Special Tools:

• MB991958 Scan Tool (M.U.T.-III Sub Assembly)

• MB991824: Vehicle Communication Interface (V.C.I.)
• MB991827 M.U.T.-III USB Cable
• MB991910 M.U.T.-III Main Harness A

STEP 2. Check whether the DTC is reset.
30 seconds after turning ON the ignition switch, check that the 
DTC is reset.
Q: Is DTC No. P0713 set?

YES : Replace the mechatronic assembly. (Refer to 

P.22C-421

.)

NO :  Intermittent malfunction. (Refer to GROUP 00 − How

DTC P0715: Input shaft 1 (odd number gear axle) speed sensor system (Output high range out)

CAUTION

• If there is any problem in the CAN bus lines, 

an incorrect diagnostic trouble code may be 
set. Prior to this diagnosis, diagnose the CAN 
bus lines.

• Whenever the ECU is replaced, ensure that 

the CAN bus lines are normal.

.

DIAGNOSTIC FUNCTION

TC-SST-ECU checks that the input shaft 1 (odd num-
ber gear axle) speed sensor is normal.

.

DESCRIPTIONS OF MONITOR METHODS

The output of the input shaft 1 (odd number gear 
axle) is determined to be too high.

.

MONITOR EXECUTION
